Question Photonuclear reactions 

Forum: Hadronic Processes
Date: 25 Jan, 2010
From: Ralph Massarczyk <Ralph Massarczyk>

Is there a possibility to describe the following reactions? - Ag + gamma -> Ag* , and after that: - Ag* -> Ag + gamma I implemented in my Physicslist

  G4GammaNuclearReaction* gammaNuclear = new G4GammaNuclearReaction();
  G4PhotoNuclearProcess* photoNuclearProcess = new G4PhotoNuclearProcess();

and for Decay:

#include "G4Decay.hh"
#include "G4RadioactiveDecay.hh"
#include "G4IonTable.hh"
#include "G4Ions.hh"

void PhysicsList::ConstructGeneral() {

  // Add Decay Process
  G4Decay* theDecayProcess = new G4Decay();
  while( (*theParticleIterator)() )
      G4ParticleDefinition* particle = theParticleIterator->value();
      G4ProcessManager* pmanager = particle->GetProcessManager();

      if (theDecayProcess->IsApplicable(*particle) && !particle->IsShortLived()) 
	  pmanager ->AddProcess(theDecayProcess);
	  // set ordering for PostStepDoIt and AtRestDoIt
	  pmanager ->SetProcessOrdering(theDecayProcess, idxPostStep);
	  pmanager ->SetProcessOrdering(theDecayProcess, idxAtRest);

  // Declare radioactive decay to the GenericIon in the IonTable.
  const G4IonTable *theIonTable = 
  G4RadioactiveDecay *theRadioactiveDecay = new G4RadioactiveDecay();

  for (G4int i=0; i<theIonTable->Entries(); i++) 
      G4String particleName = theIonTable->GetParticle(i)->GetParticleName();
      G4String particleType = theIonTable->GetParticle(i)->GetParticleType();

      if (particleName == "GenericIon") 
	  G4ProcessManager* pmanager = 
	  pmanager ->AddProcess(theRadioactiveDecay);

	  pmanager ->SetProcessOrdering(theRadioactiveDecay, idxPostStep);
	  pmanager ->SetProcessOrdering(theRadioactiveDecay, idxAtRest);


But unfortunally I see no gammas from excited states, only if I use excited nuclei oder radioactive nuclei as PrimaryParticles. But I need the excitation also. Is this case described somewhere in one of the examples?

I read something about a G4NRF package, is this still available?

Thanks for your help
